Association of an intronic haplotype of the LIPC gene with hyperalphalipoproteinemia in two independent populations.
Article in Journal of human genetics, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hepatic lipase (HL) plays a major role in the regulation of plasma lipids. Several groups seeking to find association between the gene encoding HL (LIPC) and plasma concentrations of high-density lipoprotein cholesterol (HDLc) using various methods and populations have reported conflicting results. We have approached the problem of demonstrating a relationship between the LIPC locus and HDLc by means of haplotype association using four single nucleotide polymorphisms (SNPs) (rs12594375G/A, rs8023503C/T, rs4775047C/T, and rs11634134T/A) located in intron 1 of the LIPC gene in two independent Japanese populations consisting of 2,970 and 1,638 individuals, respectively. Significant association between hyperalphalipoproteinemia and a specific haplotype in this intron was detected in both populations. When HDLc levels among the three haplotypic categories were analyzed [haplotype rs8023503C/rs12594375G (haplotype-1; H1) homozygotes (H1H1), haplotype rs8023503T/rs12594375A (haplotype-2; H2) homozygotes (H2H2), and heterozygotes (H1H2)], HDLc levels were lowest among H1H1 [mean +/- standard error (SE) = 58.4 +/- 0.4 mg/dl], highest among H2H2 (62.5 +/- 0.8 mg/dl), and intermediate among H1H2 (59.2 +/- 0.4 mg/dl) (P = 0.00011), indicating that H2 haplotype elevates plasma HDLc levels. This association was validated in the second population (n = 1,638) (P = 0.00070). The results provide convincing evidence that the LIPC locus influences HDL metabolism.
